Problem:

Previously in Ethereum Network, additional tools were required in order to transfer many ERC20 tokens at once. Many people still do this manually, one transaction at a time. This process is time consuming and prone to an error.

Solution:

This Dapp allows a user to send thousands of token transfers in a very effecient way by batching them in groups of 145 token transfers per Ethereum transaction. This automation saves time by automatically generating transactions to MetaMask. Finally, this tool allows a user to maintain security of their account by delegating the trust of their private keys to a secure MetaMask wallet.

How to use:

  1. Install Metamask.
  2. Make sure you have an account in MetaMask which has a token balance.
  3. Make sure your MetaMask is pointed to the network that you would like to use.
  4. Make sure your MetaMask account is unlocked.
  5. Go to https://rstormsf.github.io/multisender/#/
  6. Wait for the full page to load.
  7. Select a token from the dropdown that you would like to send.
  8. Provide either JSON or CSV text in the textarea (see example below).
  9. Click next.
  10. If everything looks good, click next once again.
  11. Wait for MetaMask to generate an approval transaction.
  12. Once the approval transaction is mined, MetaMask will generate as many transactions as needed for your token transfers (145 addresses per tx).
  13. Done!

You can test this tool on any test network, if you want to make sure that everything will work as expected.

How to setup dev environment

  1. git clone git@github.com:rstormsf/multisender.git
  2. cd contracts
  3. I used node -v v9.7.1
  4. npm install
  5. deploy MultiSender contract OR use existing deployed version: 0xa5025faba6e70b84f74e9b1113e5f7f4e7f4859f currenty deployed on Kovan, Rinkeby, Ropsten, POA-network, POA-Sokol, Mainnet Instructions on how to deploy it is listed below.
  6. cd ..
  7. npm install
  8. cp .env.example .env
  9. open .env file and provide an address of multisender contract
  10. npm run start

Contract Deployment

There are 2 ways to deploy the contracts: Upgradable and non-upgradable way. Non-upgrdable:

  • cd contracts
  • npm run flatten
  • take flats/UpgradebleStormSender_flat.sol and deploy it using https://remix.ethereum.org/
    • select solidity 0.4.23 version in settings
  • once deployed, call initialize function with parameter address of owner’s contract

Disclaimer

This tool is not affiliated with https://poa.network This is a personal project of Roman Storm.

He is not responsible for any loss from transactions derived by MultiSender. Some of the underlying JavaScript libraries and Ethereum tools that were used are under active development. The website and smart contract has been thoroughly tested, there is always the possibility something unexpected happens resulting in losses of Ethereum and/or tokens.

Any ERC20 tokens you transfer to the Multisender will be sent out to the addresses that you provided.

The smart contract source code can be audited by anyone in this repository.

I encourage you to assess its security before using the Mutlisender Dapp.

问题:

以前在以太坊eth网络中,需要额外的工具才能一次传输多个ERC20令牌。很多人仍然是手工操作,一次一个事务。这个过程非常耗时,而且容易出错。

解决方案:

此Dapp允许用户以非常有效的方式发送数千个令牌传输,方法是将它们按每个以太坊eth事务145个令牌传输分组。这种自动化通过自动生成到元掩码的事务来节省时间。最后,此工具允许用户通过将其私钥的信任委托给安全的元掩码钱包来维护其帐户的安全性。

如何使用:

  1. 安装元掩码。
  2. 确保您在MetaMask中有一个具有令牌余额的帐户。
  3. 确保元掩码指向要使用的网络。
  4. 确保元掩码帐户已解锁。
  5. 转到https://rstormsf.github.io/multisender/#/
  6. 等待加载整个页面。
  7. 从下拉列表中选择要发送的令牌。
  8. 在文本区域中提供JSON或CSV文本(参见下面的示例)。
  9. 单击“下一步”。
  10. 如果一切正常,请再次单击“下一步”。
  11. 等待元掩码生成审批事务。
  12. 一旦挖掘了审批事务,MetaMask将生成您的令牌传输所需的任意多个事务(每个tx有145个地址)。
  13. 完成!

您可以在任何测试网络上测试此工具,如果您想确保一切都按预期工作。

免责声明

此工具与https://poa.This网络是罗马风暴的个人项目。

他对多卖方交易产生的任何损失概不负责。所使用的一些底层JavaScript库和以太坊eth工具正在积极开发中。网站和智能合约已经过全面测试,总是有可能发生意外的事情,导致以太坊eth和/或代币的损失。

您转移到Multisender的任何ERC20代币都将发送到您提供的地址。

此存储库中的任何人都可以审核智能合约源代码。

我鼓励您在使用Mutlisender Dapp之前评估其安全性。
